Application filed December 19, 1916. .Serial No. 137.820.

To all whom it may concern.-

- which the wheels at one side of t Be it known that I, WILLIAM L. PAUL,a citizen of the United States, and resident of San Francisco, in thecounty of San Francisco and State of California, have invented certainnew and useful Improvements in Engine Gang-Flows; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappentains to make and use the same.

This invention relates to improvements in plows and more particularly tosuch as employ a tractor as the draft means and known in the art asengine gang plows.

One object of my present invention is to so construct an engine gangplow that the plow bases shall be caused to conform to the contour ofthe ground regardless of the hard and hilly or miry condition of thesame and thus insure uniformity of depth of plowing under all andvarying conditions of the ground being worked.

A further object is to provide an engine gang plow structure which shallembody a .rlgid beam extension connected with the forward portion of thetractor and so that the draft means for the gang may be connected withan intermediate portion of the latter and with the tractor in proximityto or in rear of the rear axle thereof.

A further object is to so connect a plow gang with a tractor, as toprovide a floating plow connected close to the tractor and employing agage wheel so located with respect to the plow bases that the latterwill be. caused to adapt themselves to the contour of the ground.

A further object is to provide simple and efficient means in an enginegan plow in e tractor run in the furrow, to quickly adjust the gang tolevel the same relatively .to the lateral inclination of the tractor andlevel said gang with respect to the ground;

A further object is to provide a draft device in an engine gang plowstructure which shall have its rear portion which is connected with theplow, disposed at such angle with respect to the tractor as to maintainthe plow level with the round when the tractor is inclined lateral y byreason of the running of the wheels at one side of the latter in thefurrow.

. upwardly from the beams of the plow units A further object is toprovide a draft device between the tractor and the plow gang, whichshall be so corelated to these members of the structure that duringforward working movement, the plow bases will be drawn downwardly andcompelled to enter and remain in hard ground, and so that when thestructure is backed, the plow bases will be caused to rise and thus rideout of the ground.

With these and other objects in view the invention consistsin certainnovel features of construction and combinations of parts ASSIGNOR T0OLIVER GHILIIED as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of an enginegang plow structure embodying my improvements; Fig. 2 is a plan View,and Fig. 3 is a rear diagrammatic view.

1 represents a tractor (the forward end portion and front Wheels ofwhich are omitted) and 2 the mounting for the rear axle 3 with which therear tractor wheels 4 are connected.

In the present instance I have shown a plow gang 5 comprising two plowunits, 6, 7 (although a greater number of plow units may be employed, ifdesired), and the rear ends of these plow units may be rigidly connectedby means of a brace 8. The beam of vthe plow unit 6 may extend forwardlyover the rear axle of the tractor, while the beam of the plow unit 7 maybe provided at its forward end with a lateral arm 9 projecting towardthe beam of plow unit 6, and to said lateral beam arm, an arm 10 at therear end of a beam-extension 11 is securely bolted. The beam'll is alsobolted to the beam of the plow unit 6 and extends downwardly andforwardly from the same. The beam 11 thus const1tutes a beam extensionfor the gang and its forward end is made to project loosely through anopening 12 in a bracket 13 near the forward portion of the tractor andnear-one side thereof,-thus effecting a guiding and supportingconnection for the plow gang to the tractor at a point well in advanceof the rear axle of said tractor.

Brackets 14, 15 are secured to and project 67 at points somewhat in rearof their connected forward ends, and these brackets I a toothed segmentsecured at one end to the bracket 15 and at the other end to the.

are made with openings to accommodate the mounted in bosses 19 on therear axle mounting of the tractor. The opening in the bracket 15 throughwhich the cross bar of the bail passes is made elongated and adjacent tothis bracket, a link 21 is loosely connected with the cross bar 16 ofthe bail and depends therefrom. The lower arm 22 of a hand lever 23 isconnected with the lower end of the link 21, said hand lever beingpivoted at 24 to the plow unit 7 and is provided with a suitable detentto engage plow unit 7.

It will be observed that with the construction above described,-the plowgang is connected with the rear portion of the tractor through themedium of the bail 17; that the beam extension 11 of the gang is looselyconnected with the forward portion of the tractor and is supported bythe latter so that the gang bases may rise and fall to conform to thecontour of the ground, the forward connection of the beam extension tothe tractor constituting a fulcrum for the plow gang.

In order that the conformity of the bases of the plow units to thecontour of the ground shall be accurate and uniform depth of plowing bethus insured, I provide a gage wheel 26 located approximately betweenthe points of the two plow bases. The standard 27 of this gage wheelwill be adjustably connected with the beam of the plow unit 6 by meansof a suitable clamp, such for instance, asillus'trated at 28.

In engine gang plow structures in which the plow gang is connectedcomparatively close to the rear of the tractor, the wheels at one sideof the latter may run .in the furrow and hence the rear axle would beinclined laterally. It is important however, that the plow gang shall beso disposed that it shall'be level with the land, and for this reason,the bail 17 is so formed that one end ofits cross bar 16 shall be higherthan the other end, as shown in Fig. 3, thus causing said cross bar toassume a position at-an angle to the plane of the rear axle of thetractor. With such arrangement, it is evident that when the plowstructure isat work with the wheels at one side of thetractor running inthe; furrow, the cross bar 16 of the bail will maintain an approximatelyhorizontal position and the plow units will be kept in position to runat uniform depths. It is desirable however to be ableto accurately leveltheplow units so that they shall be caused to run at uniform depthsunder all conditions, as when the plowing is .first begunor when theplows are adjusted to connection with the rear change the depth ofplowing. This can be readily accomplished by manipulation of the anduniform plowing.

To provide means for raising the plow gang, I may employ a manuallyoperable lever. In the present instance, a hand lever 29 is pivotallymounted on the rear axle mounting 2 of the tractor and provided with arearwardly projecting arm 30 having a roller 31 mounted at its rear end,said roller being disposed to engage the under side of the beam of theconnected plow units only when operated to raise the gang. A toothedsegment 32 is secured to the axle mounting 2 and the lever 29 isprovided with a suitable detent to engage said segment.

By reference to Fig. 1 of the drawing, it will be observed that theconnection of the rear end of the bail 17 with the plow gang is in ahigher plane than is the pivotalconnection of the forward end of thebail with the tractor, and hence said bail inclines forwardly anddownwardly from its connection with the plow gang- This is importantbecause it causes the plow bases to be forced into the ground and keptproperly in hard ground as the plow structure moves forwardly, and onthe other hand it causes the plow bases to run out of the ground whenthe Various changes might be made in the details of construction of myinvention without departing from the spirit of my invention or limitingits scope and hence I do not wish.

torestrict myself to the precise details herein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is
